Screen Time at 6 Years Old and Visual Function in Early Adolescence.

Excessive screen time has been linked to adverse health outcomes in children, including vision-related problems such as myopia. However, very few studies have evaluated the effect of moderate screen exposure on the development of visual functions. This study aimed to examine the association between screen time during middle childhood and color discrimination, contrast sensitivity, and short-range visual acuity in 12-year-old children ( = 305) from the mother-child PELAGIE cohort (France) for the whole sample and for boys and girls separately.
